POSITIVE SHUTTLE-MOTION FO'R LOOMS.

SPECIFICATION forming part of Letters Patent No. 320,902, dated June 23,1885.

Application filed September 29, 1883. (N model.)

To all whom it may concern.-

Be it known that we, FREDERICK K. WRIGHT, CHARLEs W. GAGE, and WILLIAMF. HITCHCCCK', citizens of the United States,

residing at Homer, in the county of Cortland and State of New York,haveinvented certain new and useful Improvements in PositiveShuttle-Motions for Loo-ms; and we do hereby declare the following to.be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

Our invention is an improvement in positive shuttle motions such asareemployed in looms for weaving wire and other cloth.

It consists, chiefly, of a pair of picker-staffs for moving theshuttle-carriers, which are united to the said shuttle-carriers byribbons, said staffs being moved laterally by means of levers pivot-edon a bracket secured to the beam of the lay or beater, connecting armsor rods between the said levers and pickerstaffs, bars provided withcam-grooves fixed to the loom-frame, and arms or rods guided upon 2 5the lay-frame, connected with said levers, and

provided with projections or rollers fitting into said cam-grooves, allof which will be set forth hereinafter.

In the drawings, Figurelis a sectional view of a portion of a loom,showing the shuttle motion in elevation. Fig. 2 is a plan View showingthe shuttle operating mechanism. Figs. 3 and 4 sh 0w details of partshereinafter described.

3 5 Referring to the drawings, A is the beam of the lay, provided ateach end with plates a a, formed into loops a, which latter serve asguides for the shuttle carriers B B, and the curved rocker-arms F F ofthe picker- 0 staffs D D. The carriers B B have 1ongitudinal grooves d don both sides, into which the tongues or projections e e on the opposingfaces of the plates a and loops a extend, and serve as accurate guidesfor the carriers.

5 To the ends of the shaft 0, which forms the axis of motion of the lay,are pivoted on suitable clips or clasps,b b, the pickerstafi's D D, foroperating the shuttle-carriers. Ribbons f f are secured adj ustably atopposite ends to the heels of the rocker-arms F F and the inner ends ofthe carriers, respectively, while similar ribbons, f 2 J, are securedadjustably to the toes of said rocker-arms and the outer ends of thecarriers,respectively. The rocker-arms F F are united to the tops of thepickerstaffs, near the heels of the arms, so as to permit the said armsto reach inward across the machine to as great an extent as possible.

G is abraeket secured to the beam A of the lay, which serves as abearing to ashaft which forms the fulcrum of shear-levers H H. Toopposite ends of said levers are pivoted arms I I and rods K K. Thepicker-staffs D D have pivoted in the slots 0 the rodsKK,which lattermay be adjusted in the said slots by any well-known and suitable means,to change the throw of the picker-staffs to suit circumstances.

To the ends of the arms I 1, upon suitable pins, are securedanti-friction rollers g g. Plates J J, grooved on their under edges, are7c secured to the lay-beam A, and these plates, together with shortextensions j on the arms I I, serve as guides to the latter as they aremoved back and forth.

L L are bars formed with cam-grooves,which 7 5 are U-shaped in verticaltransverse section, and have the general conformation shown in thedrawings, said bars beingpermanentlyfixed to the upper horizontal beamsof the loomframe and braced together by a rod, h. The SC grooved bars LL form races for the movement of the anti-friction rollers g g, andduring the reciprocating or swinging movement of the lay the carriers BB receive the proper movement through armsI 1', levers H H,rods KK',picker-staffs D D and the ribbons uniting the rocker-arms F F withsaid carriers. I

Motion is given to the lay in the usual manner by cranks A on the mainshaft A of the loom, and rods A, connecting the lay with or such cranks,and, as previously implied, the movement of the mechanism composing theshuttle-motion described is coincident with the movement of the saidlay.

The shuttles to be used with our shuttle-mo- 9 tion are such as areadapted for use with carriers that alternately take hold of and releasethe same automatically-such, for instance,as is shown and described inthe patent to F. K. W'right, No. 299,610, June 3, 188i. 1

The bars in which the cam-grooves are formed are so shaped that whenmotionis imparted to the carriers aslow impulseis given atstarting,which is quickened at the center of the stroke, and then retarded, sothat the liability to concussion at the moment of change of the shuttlefrom one carrier to the other is obviated.

In Fig. 4 of the drawings we show the end of the rocker-arm F with a lugsecured thereon, and the ribbon f provided with a screw threaded end anda nut, f. Said arrangement is for the purpose of tightening or looseningsaid ribbon as it is lengthened or shortened from any cause. A similararrangement may be applied to the outer ends of the carriers B B, asindicated in Fig. 1.

Having thus described our invention, what,

we desire to claim and secure by Letters Patent is 1. The combination ofthe lay, the carriers, the flexible ribbonsff ff the rocker-arms F F,connected to the carriers by said ribbons, the picker-staffs D D, unitedto the rockerarms near the heels of said arms, and the camgrooved barsLL, with shear-levers H H, the connecting-arms I 1, secured at theirinner ends to the tops of the levers H H, and at their outer ends beingprovided with the rollers g to enter the cam-grooves, and theconnecting-rods K K, connected at their inner ends to the lowerlimbs ofthe lovers H H, and

at their outer ends to the picker-staffs, and means for operating thelay, substantially as and for the purpose specifie 2. The combination ofthe lay, the carriers, the picker-staffs, means for connecting thecarriers and the picker-stairs, and the camgrooved bars L L,with theshear-levers H H, the connecting-arms I I, secured at their inner endsto the tops of the levers HH, and at their outer ends being providedwith rollers g to enter the cam-grooves, and connecting-rods K K,connected at theirinner ends to the lower limbs of the levers H H and attheir outer ends to the picker-staffs, and means for operating the lay,as and for the purpose set forth.

3. The combination, with the frame and can1- grooved bars fixed thereto,of the lay, the shuttle-carriers, the picker staffs, ribbons connectingthe carriers and picker-staffs, and levers and rods, substantially asdescribed, for imparting motion to said picker-staffs from the saidcani-grooves'as the lay vibrates, as and for the purpose set forth.

In testimony whereof we affiX our signatures in presence of twowitnesses.
